IMPROVEMENT IN SASH-FASTENER'S.

Specitication forming part of Letters Patent No. 179,720, dated July 11, 1876; application filed March 30, 1876.

To all whom it may concern:

Be it known that 1, JOHN W. MORSELL, of the city of Washington, District ot' Columbia, have invented a new and useful Improvement in Window-Fastenings, which improvement is fully set forth iu the following specification, reference being had to the accompanying drawing.

'lhe object of my invention is to combine security and ventilation in windows; and it consists in a novel construction and combination of a perforated stationary plate, A, corresponding perforations in the upper sash B, a spring, d, actuating a bolt, c, through a hole in the lower sash D, and into the pert'orations in the stationary plate aud upper sash, and a lever, e, for withdrawing the bolt from the uppersash and stationary plate, as hereinafter more fully described.

The perspective View, Figure l, of the accompanying drawing' shows both sashes closed and the bolt withdrawn. Fig. 2 ofthe drawing is an elevation, the lower sash being slightly raised and the upper, one lowered, to give a current of ventilation, and the bolt allowed to spring into place through the sashes and the plate A, thus eectually locking the window.

It will be seen that the spring d is a flat steel spring attached to the sash by means of screws, and that it is here drawn of a peculiar shape, being wider where the screws are inserted, that it may retain equal strength throughout, and that it has aprojection at Z, against which the lever rests when the bolt is fully withdrawn. It could, evidently, be made in other form or contour, so long as it performs the duties herein assigned to itgbut the one shown is preferred.

It will also be observed that the lever c is a flat piece of metal, or other hard substance, inserted under the spring, and attached to the sash by means of small sta-ples, and that it has a shoulder projecting from one side of the spring and curled back as a purchase. It may beattached to the sash in any manner found practicable, and made in any other shape. When the lever is drawn back till the shoulder strikes against the projection Z in the spring, as in Fig. 1, the bolt is withdrawn from the upper sash and the plate A, and will remain so, allowing the sashes to be moved at will, until the lever cis forced out of its position and the spring allowed to actuate the bolt. The boltc is shown as riveted to the spring, which is thought the preferable manner; but it may be attached in any feasible way.

Fig. 3 is a vertical section through Fig. 2, at the line a a. The same letters are used to denote the same features throughout the drawing. It will be noticed iu this figure that the frame of the upper sash B is faced at one side by a metallic or other durable plate, fi, with pertorations corresponding to those in the sash. This is to prevent the sash from being worn or grooved on account of any friction from the bolt c, and for the protection of the perforations, which are made a little larger than the bolt. Obviouslythe operation would be the same without it; but the construction would not be so durable and efficient. In Fig. 3 plate i is merely attached Aupon the surface of the sash, as iu practice it may generally be done,-a groove being cut through the bevel of the lower beam of the sash large enough to admit both plates,

as shown at j, Fig. 3; or the whole bevel may be cut otf at the end, if desired, to the .width of the plates, as is a portion of the bevel of the lower sash, as seen at k in Figs. l and 3. Where necessary the plate may be let into the sash B. The stationary plate A is, in this figure, let into both the frame C and the strip'h. In most cases it may be merely fastened upon the surface of the frame C by sunk screws or otherwise, as shown in Fig. 4, or upon both the frame and the strip, as there is generally sufficient play between the sash and the frame to admit of it 3 and the windowcordfwill not be atfected thereby, it hanging away from the frame, asshown in Fig. 4; or it may be fastened to the frame (.l under the strip h; or, it' desired, the plate A may be attached directly to the strip, as in Fig. 6, dispensingl with that part of the plate which is screwed against theframe iu Fig. 4; or it may be made in conjunction with the strip, and of one and the same piece, as in Fig. 7. The plate A may have any practicable shape. Fig. 5

represents a variety ofits JForm, having lian ges g g g projecting' at right ang-les from vthe side ot' the plate, and by which it'is'fasteued to the frame.

I claim as my invention- 1. In combination with the upper and lower sashes, each perforated in its side rail, a perforated plate, A, secured atthe side of the window-frame, and heldrinly throughout its length, al1 substantially as and for the purpose set forth. y

2. In combination with a spring, d, provided with an attached bolt, c, adapted to enter perforations in both sashes of a window, the lifting-lever e, applied as described, and serving not only to withdraw the bolt, but also to hold it Withdrawn, `substantially -as shown and described.

3. The combination of the perforated pfate A, fixed to the frame of' the window between the sashes, the perforated plate i on the upper sash, the springboltc d upon and Working through the lower sash, and through the plate A into the upperv sash, and the lifting and Withholding Vlever e, all substantially as and for the purpose set forth.
